Abstract
We argue that the validity of the WKB approach for calculating nonequilibri um properties of a nonlinear stochastic system requires an additional crite rion involving the time interval, compared with the standard WKB criterion considered by Mannella [R. Mannella, Phys. Rev. E 58,2479 (1999)]. In order to clarify the situation, we compare the WKB solution with the direct nume rical solution of the Fokker-Plank equation.
